5G (5th Generation mobile communication system) has been commercialized, and it is expected that QoE (Quality of Experi-ence) will be significantly improved by the eMBB (enhanced Mobile Broadband) technology. Meanwhile, communication traffic is continuously increasing, and thus, even if 28 GHz band is widely used, there still has a serious problem of spectrum resource shortage. Therefore, it is necessary to introduce new technologies for expanding the system capacity in B5G (Beyond 5G). The authors have researched and developed an IBFD (In-Band Full-Duplex)-based cellular system for improving spec-trum efficiency. In general, IBFD induces an SI (Self-Interference) to the receiver and degrades the communication quality. In this study, we implement an analog SI canceller in the IF (Intermediate Frequency) circuit of the IF-based RF (Radio Frequen-cy) front-end of the multi-band base station and apply IBFD to the communication in the 28 GHz band. Also, we prototype an RF front-end and evaluate the SI cancellation performance for 4.7 GHz and 28 GHz bands assuming Local 5G. |
